Description of the invention (1) Background of the invention The present invention relates to a method of manufacturing a resin-encapsulated semiconductor device. More particularly, the present invention relates to a method of injecting an epoxy resin compound into an injection molding die to manufacture a resin-encapsulated semiconductor device, in which the lead frame where the semiconductor has been bonded and wired is fixedly set as an insert in an injection molding Mold and harden the epoxy resin compound in the injection mold. Description of Related Art In the packaging of semiconductor devices such as IC and LS I, conversion molding methods using epoxy resin molding compounds have been widely used because of their low cost, high reliability, and high production efficiency. Generally speaking, in conversion molding, the epoxy resin molding compound forms a piece, and this piece is filled into a pot in the mold, and this piece * is pressed by a plunger when it is melted by heat in the mold. Therefore, the molten molding compound can flow and then harden. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) Shape), and therefore requires a forming step. Depending on the size and shape of the semiconductor device, the shape of the sheet will vary widely, so many molding devices are needed to form the epoxy molding compound. Since each molding operation requires the hot-energized sheet and the molten sheet, the period of the molding cycle cannot be reduced to a predetermined period of time, which limits cost reduction and productivity. Furthermore, impurities may be introduced into the molding compound in a pre-processing step (such as a forming step). In the conversion molding, in the flow path where the molding compound is charged into a pot, the residual stream flows into the mold cavity, and in the pot The finished paper scale is applicable to the Chinese National Standard (CNS) A4 (210X297 mm). 4 The A7 B7 is printed by the Male Workers ’Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention (2) is fully hardened, so they can no longer be used. The problem caused by this is that a large amount of resin that is not used to form a semiconductor package is wasted. On the other hand, injection molding methods using thermosetting resin molding compounds such as epoxy resins have been studied so far. In this injection molding, the epoxy resin molding compound in the form of powder or granules is supplied to an injection molding machine, kept molten in a cylinder, and injected into a mold with a screw rod. Therefore, the step of forming the epoxy resin molding compound into one piece is unnecessary, and it can also be continuously produced. Therefore, the apparatus for forming purposes and the time for forming can be omitted. Furthermore, since the molding material in the molten state is shorter than in the conversion molding, this method is suitable for mass production. However, injection molding of epoxy resin molding compound encapsulation is not actually used. The reason is that the molten state of the conventional epoxy resin molding compound is heated to 70 ° C-110 ° C in the cylinder, and when the resin hardening reaction in the molding compound proceeds, the viscosity of the molding compound increases. As a result, its fluidity is lost for 5 to 10 minutes, and the thermal stability of the molten molding compound is extremely low. Therefore, it is impossible to perform injection molding at low pressure, and therefore, high pressure injection is not required. As a result, the bonding wires on the semiconductor device will be deformed or cut, and therefore, the reliability of the resulting semiconductor package will be significantly reduced. Another problem with the conventional art is that when the molding operation is interrupted for a predetermined period of time (for example, to clean the mold), the epoxy molding compound will harden in the cylinder, so it can no longer be injected, and therefore will have a reverse effect Continuous production.

The epoxy resin molding compound used in the present invention usually contains an epoxy resin, a hardener, a hardening accelerator and an inorganic filter as its main components. It is often in the form of powder or granules. When in conversion molding, it need not form a piece. The epoxy resin molding compound preferably exhibits good thermal stability in the cylinder of the injection molding machine, good fluidity in the cavity, and rapid hardening. In view of the above description, epoxy resins can be those with low melt viscosity, such as novolac epoxy resins and bisphenol resins, and especially have a softening point of 50 ° C-80 ° C. Regarding the hardener, phenolic resins such as novolac phenol resin, p-xylyl modified phenol resin and dicyclopentadiene modified phenol resin can be used, and especially those having a temperature of 60 to 120 ° C Phenolic resin that softens the point and contains the contents of monocaryon and di car yon. As for the hardening accelerator, for example, diazabicycloundecene (DBL) or organic phosphine such as triphenylphosphine can be used, and the hardening accelerator is preferably in a high latent state exhibiting low activity at low temperatures. In the present invention, runnerless molding or runnerless molding can be used. More specifically, the temperature of the runner portion of the mold or the temperature of the runner portion and runner portion is controlled to a temperature at which the molding compound is hard to harden, that is, approximately equal to the temperature in the cylinder. By this, the uncured resin compound remaining in the residual channel portion or the runner runner portion can be filled into the cavity at the next step after the molded product (ie, resin-encapsulated semiconductor device) is removed or taken out In this, the paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) ----- r --- 1 1 ^ ------. ^ 1 ------ ^ (please first Read the precautions on the back and then fill out this page) -7-311270 A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Economics of the Ministry of Economic Affairs V. Description of the invention (5) Used to effect the molding. Therefore, any molding compound that is not a molded product cannot be formed, and therefore, a significant reduction in resin waste can be achieved. In the package molded by general conversion, the ratio of the hardened resin waste and the entire molding compound in the flow channel portion is 40% ~ 60%, but in the injection molded package of the present invention, the hardened resin waste The ratio is slightly reduced to 30%-50%, and in non-runner molding, this ratio can be further reduced to 2 5% ~ 3 5%, and in runnerless runner molding, this The ratio is further reduced to 10% ~ 30%.

One embodiment of the present invention is characterized in that the injection pressure of the injection molding machine is When 80%-95% of the total injection volume of the compound is injected into the mold, it will increase to the maximum pressure, which is between 30 kg / cm2 and 300 kg / cm2. The remaining molding compound is injected at an injection pressure of 20 kg / cm2 to 100 kg / cm2. In this case, the ratio of the latter pressure to the former maximum pressure is preferably 1/4 to 1/2. If the two pressures are higher than the above values, the bonding wiring on the semiconductor device may be deformed and cut off. Conversely, if the two pressures are lower than the above values, the molding compound cannot be properly filled into the mold cavity . Preferably, the maximum injection pressure is in the range of 100 kg / cm2-250 kg / cm2, and the pressure of the latter is in the range of 40 kg / cm2-120 kg / cm2. The size of the paper used for injection of general thermosetting resin is applicable to the Chinese National Standard (CNS) A4 (210X297 mm). 9 Printed by the Central Bureau of Standards of the Ministry of Economic Affairs, 311270 A7 _ _B7 _ ^ _ V. Invention Description (7) For comparison, the injection pressure is lower. Since the injection pressure is low and temperature control can be performed more easily, continuous operation can be performed under low pressure. Since this molding can work under low pressure, the deformation degree of the combined wiring is low. Therefore, the lead frame mounted with semiconductors can form a finer pattern. The semiconductor-bonded lead frame is fixedly set so that an insert is in the mold, and then the mold is closed or clamped. The molding compound is injected into the mold. The molding compound is at a generally sleepy rate from the beginning of filling to reaching the maximum injection pressure. If the filling of the molding compound is not continuous, the maximum pressure will be reached at 100% of the filling effect. Even if the value of this maximum pressure is quite small, this pressure will directly act on the molded part during the filling operation. In the final stage, deformation or disconnection of the joint wiring will occur. Therefore, according to the present invention, the injection pressure is slightly reduced before the filling is completed, and therefore, the filling can be continued at a low pressure. Therefore, it is possible to prevent deformation or cutting of the joint wiring. The set temperature of the cylinder is usually 65 ° C to 110 ° C, and temperature control in this range is quite easy. However, due to melt viscosity and thermal stability and considerations, this setting temperature is preferably 70 ° C to 90 ° C. If the cylinder temperature is low, although the melt viscosity is high, the hot spike is well qualitative. In the epoxy resin molding compound of the present invention, especially when the above preferred composition is used, the melt viscosity is low, and therefore the cylinder temperature can be set to a relatively low level. However, if the cylinder temperature is set below 65 ° C, temperature control of the molded compound becomes quite difficult. Conversely, if the temperature of the cylinder is higher than 110 ° C, the melt viscosity is too low. Therefore, although proper injection is sometimes used, in addition, satisfactory thermal stability cannot be achieved. ^ iT ------- ^ I * —. * (Please read the notes on the back to fill in this page first) This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 10-A7 _B7_ 5 2. Description of the invention (8) In the embodiment of the present invention, due to the curing time of the molding compound, etc., the set temperature of the mold is 150 ° C to 190 ° C and preferably 165 ° C to 1 85 ° C. With this temperature setting, the molding cycle does not exceed 150 seconds, and in the case of a molding compound of a preferred composition, the molding cycle does not exceed 80 seconds. Example 1 The main components of the epoxy resin molding compound used here include an original cresol novolac epoxy resin (epoxy equivalent 200), phenol novolac (hydroxyl equivalent 10 3), diazabicyclo Undecene (hardening accelerator) and fused silica, and another with a mold release agent, a dye, etc. In this example, a screw linear injection molding machine (M-3 produced by Me iki Seisakusho company) is used 2 ). The area of the heated cylinder closest to the nozzle, printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, is 30% of the total length of the cylinder and is kept at 75 ° C, while the other area of the cylinder is kept at 30 ° C. Regarding injection pressure, the maximum pressure is 200 k g / cm2. The injection pressure rises to the maximum pressure in 20 seconds from the start of injection. Then, lower to 50 k g / cm 2 and hold for 5 seconds, and then operate the gate cut pin to close the gate. The relationship between injection pressure and screw position or injection pressure time is shown in Figure 1. The time period from the closing of the mold to the start of the mold is 60 seconds, and the entire molding cycle is 80 seconds. The temperature of the mold is set to 17 5. . . This mold is a twenty-cavity mold.

Description of invention (9) 1 0 IC components (16-pin double-row configuration) The two lead frames set in sequence are automatically set in the mold, and this mold is executed continuously. The appearance, filling capacity, wiring swing, and surface hardness of the resin-encapsulated semiconductor device are measured every hour. The results are shown in Table 1.

Invention description (10) Swing amount of combined wiring (diameter of semi-hard gold wire 2 5 and length 3mm) »Wiring swing is expressed as the ratio of the maximum wiring swing to the distance (500 # m) between the bonding wires. (3) Surface hardness: The surface hardness of the molded product just after the mold is opened is measured by the -Barcol hardness testing machine (# 9 3 5 measurement). The results shown in Table 1 are similar to those obtained by conventional low-voltage conversion molding, and there is no problem here. Therefore, continuous molding can be performed for a long time. _ In another embodiment of the present invention, the heating cylinder of the injection molding machine is divided into a plurality of regions in the axial direction. The number of this area is at least two, and the number of areas is not limited to a specific number. However, it is better to have four or five zones. The temperature of these areas is controlled independently. For continuous molding which is more stable than conventional molding, the temperature of the area closest to the nozzle (hereinafter referred to as " ^ nearest nozzle side area #) is controlled at 6 5 ° C — 1 1 0 ° C, and the closest to the funnel The temperature of the area (hereinafter referred to as the 'nearest funnel side area') is controlled between the normal temperature and 50 ° C. The temperature of the former is preferably 70 ° C to 90 ° C, and the temperature of the latter is preferably 30 ° C to 40 ° C. In this temperature range, the characteristics of epoxy resin molding compounds with low melt viscosity can be fully achieved, and there is no problem with thermal stability, therefore, it can function stably, for a long time, continuous molding. In this example, When the heating cylinder has two regions, the total length of the nearest nozzle side region is 20% to 40% of the total length of the cylinder. When the heated cylinder has 3 to 5 zones, the closest nozzle side zone has the same temperature and length as the above two zone cylinders. The temperature of one of the three compartments is between the nearest III ^ 1 · IIIIIIII 1- ^ I i (please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 13 Printed 311270 A7 B7 by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention description (11) The intermediate value between the temperature on the nozzle side area and the temperature on the nearest funnel side area. The higher the temperature of the spaced region, the closer the spaced region is to the closest nozzle side region. The temperature of the closest funnel side area is the same as that of the cylinders in the above two areas. The length of the area other than the area closest to the nozzle side may be appropriately determined depending on the thermal stability and melt viscosity of the epoxy resin molding compound. If the cylinder temperature is low, although the melt viscosity is high, the thermal stability is still good. In the epoxy resin molding compound of the present invention, especially when the above-mentioned preferred composition is used, the melt viscosity is low, and therefore the cylinder temperature can be set at a relatively low level. But * If the cylinder temperature becomes less than 65 ° C, temperature control becomes quite difficult. The opposite of. If the temperature of the cylinder is higher than 110 ° C, the melt viscosity is too low. In this case, although proper injection molding is sometimes used, in addition, satisfactory thermal stability is often not achieved. In this embodiment of the present invention, regarding the injection pressure of the injection molding machine, the same conditions as described above can always be used, and the same advantages can be obtained. In the embodiment of the present invention, in view of the hardening time of the epoxy resin molding compound, etc., the set temperature of the mold is usually 150 ° C to 190 ° C, and preferably 1 65 ° C to 1 85 ° C. With this setting temperature, the molding cycle cannot exceed 170 seconds, and in the case of the molding compound of the preferred composition, the molding cycle does not exceed 100 seconds.

According to the present invention, by injection molding of a rotational molding type, a semiconductor package formed with an epoxy resin molding compound can continuously act for a long time without any problem. Through the automatic action or the setting of the lead frame by the robot action, the removal of the molded product and the subsequent processing of the molded product can automatically complete the molding operation. The molding compound in powder or granular form can be supplied to an injection molding machine, and therefore, it is not necessary to perform into a sheet shape as in conversion molding. Therefore, the equipment and time required for forming the sheet can be omitted. Since no pretreatment such as sheet formation is required, it is highly unlikely that impurities will enter the molding compound. In addition, non-runner molding and non-runner runner molding can be used. Therefore, the proportion of hardened material (waste) of non-molded products can be significantly reduced.
